Meanwhile, sources tell E! News that the 20-year-old pop star is working on a new single with longtime collaborator Rock Mafia, the production team responsible for her hit "Love You Like a Love Song."

Gomez was alone (i.e., sans Bieber) and focused on making music.

"Selena is hoping to have another hit and break it real soon," says a source. "That is her main priority right now."

Over in his world 2.0, Bieber officially confirmed today that he's performing on and hosting Saturday Night Live on Feb. 9. Earlier this week he announced that Believe Acoustic, which drops Jan.29, will feature three new songs called "I Would," "Yellow Raincoat" and "Nothing Like Us."
